To all whom t may concern.'

Be it known that l, VVILsoN W. BUnsoN, u citizen of the United States,residing in Rockford, in the county of Winnebago and State of Illinois,have invented n new ond useful Improvement in Knitting-liliiohines, 0fwhich the following is n specification.

his invention relates in general lo kuit ting machines and hns for itsobject broadlyY the provision of u, knitting nnufhine ibut will knit nfiner gauze gurmeut than has heretofore been possible in the machinesprior to my invention,

Bly invention (contemplates the provision of n machine shorterreciproenting movements` and ur ranged closer together thun is possiblewith the latch needle, :ind has lalso for un objert the provision of nneedle constructed for use in such n nmchine.

Another object of my invention is the vision of n knitting needle whichwill effectively with u short knitting stroke."

Another object of the invention is the provision of e knitting` needleconstructed to require minimum space in the needle guides.

A other and highly importantobjeet of my invention is the provision of nknitting needle adapted to replace und perform all of the functions ofthe hitch needle, which Vro- Init

will operate automatienlhY in knitting and upon the mere forwardprojection und retraction of its knitting hook member.,

A still further object of the invention is the Vprovision of a needlewhich may be given e high degree of fineness nud et. the same time bestrong and durable in use.

umerous other objects 4and ndvnntziges of the invention will he apparentes it is better understood from the following den Scription whenconsidered in connection .with the accompanying drawing illustrating apreferred embodiment thereof.

On the dinwing,

The knitting hook meniber consists of a. sheet of metal folded bark uponitself at 15 und providing ui'iwiirdly extending spaced wings 1G :it thefront and a hook 17 formed et the forward end oi the junction 15 betweenthe silile portions of the member,A seid hook beim," thereafter bent upand over as indicated in Figs. l and The body of the knitting hookmember extends rearwardly from the wings i6 und up into a. portion i8edellted for engagement by the jack. A pom'ion I9 of it extends up andfornnrdlv forming n ruido for the tail of the lifting hook mem er.Rearwardly of a, point 2l e reinforcing plate is positioned between theulnvzudlxv extending parts of the sheet of the knitting hook member andthis member has the slnpe of the tail of the knitting hook member justdescribed so that the reni.' part orteil .of the lm.tting hook member isof solid laminated member 14 is provided with nn enlarged forward end 23adapted to be disposed between the wings 16 and having n bottom 24adapted to rest 15 of the sheet forming the knitting hook the is cutaway to provide a recess 25 efnin a lifting hook Q6 to be disposed justbehin and'beneuth recesses 27 in thewfol ld edges of the Wings 16 inposition to receive loop as the needle is projected'to pick u a. 28isprovied 1x1 each wing `16 and alongside these slots uiper and 'lowerlips 29 andl 31 extend out a the sides a, shortdistance and a similarlip 32 is provided on the upper edges of the construction.

wings in arallelism with the lips 29 and 31. The hea 23 of the liftinghook member is provided with two airs of oppositel; extending studs 33andj 34, the studs .3i eing adapted to be disposed in the slots28 'andthe studs 33 in position to nide upon the lips 32. From the head 23 'thelshank ofthe lifting hook member extends rearwardly and terminates in nreturn spring part 35 adapted to ress against the adjacent face of onepartition 12 of the needle guide forcing the rear side of the shankagainst the other end creating sutiicient friction to cause the reletivemovement of the needle parts as will be later described. `The shank isalso provided at its end with bent-over curved lugs .S6-above the shankof the knitting hook member, andbeneath the forwardly extending part 1.9so that this end of the knitting hook member is held to a, horizontalreciprocation. As the knitting hook moves from theI position shown inFig. 2, in which position the parts are casting off the old loop overthe new, to the position shown in Fig. l, which is the position theparts assume in the initial formation or' the new loop, the knittinghook is projectedby the jack and by reason of the friction between thelifting hook and the guides or partition 12 the forward niovement ofthe. lifting hook member is retarded until the studs 34 engage the lowerrear ends'of the grooves 28 at which time the relative arrangement ofthe lit`ting'and knitting hook member is that shown in Fig` 1. At thistime the knitting hook picks up the new yarn and the old loop has slidback into the recesses '27 and on to the lifting hook 26. Returnmovement of the knitting hook under the influence of the jack permitsthe rear end of -the lifting hook to remain stationery, the forward endrising as the studs 33 and 34 ride up the lips 31 and 32, the liftinghook 26 carrying with it the old loop and permitting it to drop oll'over the` knitting hook 17 and over the new loop c-(irried by it.

The' forward ends of the partition or guide 12 are rearwardly of therearmost positions of the studs 33 ancLsl so that these studs may extendover the ends of the partitions end any unoccupied space between theneedle guides, it only being necessary that snilicient space be thereprovided to permit the shank of the knitting hook member to move freelybetween the guides.

In order that the needles may more aecurately in their stroke, I providean extension 38 on the needle bed, on which extension the lower feces ofthe knitting mein* 'bers slide. At the outer end this extension isprovided with upwardly extending auxiliary guides 89 formed by sew-kernga raised portion of the extension, or otherwise.

Since it is not necessary, as with the -over the ne latch needle,`to*r emember to be turned sufii cient f or the old loo to ass it, the strokeis meterielly reducedJin llngth being little greater than the distancebetween the knitting hook 17 und the liftin v' hook ZG when the parteare arran ed as s iown in Fig. 1. lt will be manifest rom the foregoingsince the shank ot the knitting hook is constructed of three thicknessesof relatively thin sheet material, the space provided for them in theneedle guides may be relatively narrow and the'number or' needlescorrespondingly increased in a needle bed of' riven dimensions. Inmaking the knitting look member of sheet material and in reinforcing itas described it may be made of a high degree of fineness mid still havethe requisite strength.

It is thought that the invention and meny of its attendant advantageswill be understood from the foregoing description, and it will heapparent that various changes rney be made in the form, construction andare rangement of the parts without departing from the spirit and scop'eof the invention or sacrificing all of its material ad vantnges` theform hereinbetore desx'ribed beingmerely a preferred embodiment thereof.i
